To (all who/rt if? nanny (:oltccrnl:

Be it known that we, W ILLI'AM E. BRYANT, Ron nR'r DAvIDsoN, and G some n M. W OLCOT'J, citizens of the United States, residing at Detroit, in the county of WVayne, State of Michi gan, have invented certain new and useful 1mprovements in Visible Auxiliary Oilers 'lor Lubricators; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to condensation-displacement sight-feed lubricators; and it consists in providin such alubricator with an automatic auxiliary oiler through the medium of which oil may be supplied to the parts of the lubricator by way of the sight-feed chamber of the regular oil-feed.

The object of the invention is to provide a lubricator of the character described with an auxiliary oiler which shall be automaticin its operation and in which the arrangement is such as to enable the oil to be drawn from the supply within the reservoir and discharged through the sight-feed chamber, whereby the quantity of oil fed may be discerned and regulated according to the requirements, as distinguished from the ordinary hand-oilers commonly employed.

The common practice in the employment of auxiliary oilers upon lubricators of this class is to provide an open hand-oiler, which may be used in cases of emergency and which is lilled by hand and the contents discharged at once into the tallow-pipe for the purpose of lubricating the valves of the steam-chest and the piston in the cylinder. This piocess is necessarily slow and awkward, and by its use the distribution of oil is very irregular, nor is it possible with this arrangement to see the quantity of oil that is passing from the auxiliary oiler to the parts to be lubricated. By

means of the arrangement herein shown an automatic auxiliary oiler s provided which requires no separate sight-ieed glassdiut which is made to feed through the sigl1t-l'eed chamber of the regular ileed, obviating the employment of extra parts and at the same time onabling the operator to readily see the quantity of oil which is being fed. The means by which this result is obtained are illustrated in the accompanying drawings, in which- Figure l is an elevation of a lubricator embodying our invention, parts being in section or broken away. Fig. 2 is an exaggerated view, in sectional detail, showing the auxiliary oil-passage leading from the reservoir to the sight-feed chamber and controlled by a screw plugvalve. Fig. 3 is an enlarged sectional view through the condenser, the central sight- Feed chamber, and the top of the reservoir as taken on line 3 of Fig. l. I

Referring to the characters of reference, 1 designates the body of the lubricator, in which is situated the oil-reservoir 2. lvlonnted upon the body of the lubrieatcn' are the sight-feed features 3, containing the obscrtuition-glasses 4: of the bulls-eye type, there being within each of said sight-feed features an observa-. tion-chamber 5, the ends of which are closed by said glasses. The sight-feed features are connected to the top of the l1il ricator-body by the stems 6, which are formed integral with said body. ilvllounted upon the central sight-teed feature is the condenserT, whose interior is connected withthe reservoir by a cored passage way 8, which passes down wardlyithrough the stem (5 and communicates with the upper end of the tube 9,which depends within the reservoir, whereby the water of condensation is conveyed from the condenser to the bottom of the reservoir of the lubricator, the How of water through said passage-way being controlled by the valve 10. Extending through the condenser into the steam-pipe 1 Lis a stand-pi pc '12, whose lower end communicates with a cored passage (indicated by dotted lines .13 in Fig. 3) leading to a caliduct or steam-chamber let within the reservoir, at the top thereof, and from which lead the cqualizing-passages 15, (see Fig. 2,) passing vertically through the sight-feed features and commrmicating with the oil-discharge ports 16, with which the upper ends of the tallow-pipes 17 are connected, all of which is more fully set forth in a copending application, Serial No. 219,475. Formed through the stem of each of the sightfeed features is an oil-feed passage-way18, controlled by the feed-valve 19 and having at the upper end thereof a feed-nozzle 20,

. which projects into the sight-chamber and from which the oil ascends in drops through the water in said chamber and out the dis charge-port 16 to the tallow-pipe, as will be well understood.

For the purpose of supplying an auxiliary oiler to be used when the ordinary feed becomes stopped or is rendered inoperative from any cause an auxiliary oil-feed passage 21 is formed through the stem of the sight-feed feature which connects the top of the reservoir with the sight-feed chamber 5, said passage being controlled by a plug-valve 22, adapted to be turned by the application of a wrench. Should it be desired to employ the auxiliary oiler, it is only necessary to turn the plug-valve 22 so as to open the passage-way 21, when the oilby hydrostatic pressure will be caused to flow upwardly from the reservoir through said passage-way into the sight-chamber and through said chamber between the observation-glasses to the discharge-p0rt 16. The oil which ascends through said passageway is rendered visible through the observation-glasses, and the quantity may be regulated by an adjustment of the valve 22, whereby the flow may be maintained as constant as though the regular feed were in operation. By this arrangement an accident to the regular feed does not impair the efficiency of the lubricator, and by passing the oil from the auxiliary through the regular sight-feed the engineer is able to see the amount of oil which is being fed from the reservoir, so that the feeding of an excessive quantity of oil may be obviated and the flow of lubricant regulated in accordance with the requirements.

Communicating with the sight-chamber is a passage-way 23,controlled by a valve 24,having a hollow stem, by means of which the water may be drawn out of thesight-chamber from between the glasses when desired.

Having thus fully set forth our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a lubricator, the combination with the condenser and oil-reservoir, of a sight-feed chamber having an observation-glass therein through which the passage of the oil may be observed, said chamber having the usual coni nection with the reservoir, there being a substantially vertical oil passage-way connecting the reservoir directly with the bottom of said chamber independently of the regular connection through which substantially vertical passage-way oil may be directed past the observation-glass of the regular sight-feed feature.

2. In a lubricator, the combination with the condenser and oil-reservoir, of a sight-feed feature mounted upon the top of the reservoir having-a sight-chamber therein, observationglasses in the ends of said chamber, there being the regular oil-feed passage-way connecting the reservoir with said chamber and there being an auxiliary oil passage-way also connecting the reservoir with said chamber, whereby the oil delivered through said auxiliary oil passage-way will pass between the observation-glasses of the sight-feed chamber.

3. In a lubricator, the combination with the condenser and oil-reservoir, of a sight-feed feature having an observation-chamber with a glass therein and the usual connection with said reservoir, there being an auxiliary feed passage-way connecting said sight-feed feature with the reservoir independently of the regular connection arranged to direct the oil through the sight-feed chamber by way of said auxiliary instead of through the regular oil passage-way.

at. In a lubricator, the combination with the condenser and oil-reservoir, of a sight-feed feature mounted upon the top of the reservoir, a sight-feed chamber in said feature, opposed glasses arranged within said chamber, there being an auxiliary oil passage-way leading directly from the top of the reservoir into the lower part of said chamber at a point between said glasses, whereby the oil delivered from the auxiliary passage-way may be observed through the regular sight-feed glass.

5. In a lubricator, the combination with the condenser and oil-reservoir, of a sight-feed feature, said sight-feed feature having an observation-chamber therein provided with the usual connection with the reservoir, and also having an auxiliary feed connection with the reservoir communicating with the bottom of and discharging through said chamber independently of said usual connection.

In testimony whereof we sign this specification in the presence of two witnesses.
